The Innosonian America-C17001 Brayden Baby/Infant Replacement Lung is a single-use replacement airway lung bag engineered specifically for the Brayden Baby infant CPR training manikin. Constructed from durable, flexible synthetic polymer, this lung unit connects directly to the infant airway mechanism and double-filter system to demonstrate accurate, realistic chest rise during rescue ventilation practice. Featuring an integrated non-rebreathing valve design, it directs exhaled air away from the student to ensure hygienic, cross-contamination-free training during pediatric BLS, PALS, and infant CPR certification courses.
